Title: Lock pin for die opening control
Inventor: OGAWA MASAAKI
IPC: B29C45/26
Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To eliminate the tightening adjustment for a bolt by a method wherein elasticity is imparted in the diametrical direction by a split groove which is cut in the axial direction on the side surface from the open end part of an approx. cylindrical pin main body being integrally formed with a thread part, which is inserted and fixed to a first die, at one end, and a tensile resistant force is imparted on a second die by engaging a protruding part for engagement, which is provided on the outer peripheral surface. SOLUTION: After the thread part 5 of this lock pin 4 is engaged and fixed with a female thread of a die 3, dies are closed, and an open end part 8 of a pin main body 6 comes into contact with a bushing 11 of a die 2, and the pin main body 6 warps inside in the diametrical direction by the elasticity of a split groove 7. The inner peripheral surface of the bushing 11 slides on a slope on the outer periphery of the open end part 8, and gets over the ridge part of a protruding part 9 for engagement, and the protruding part 9 for engagement and a part 13 to be engaged are engaged, and a sufficient resistance force is imparted to the die 2.  When the dies are opened, movable dies 2, 3, while being integrally combined, separate from a fixed die, and the movement of the die 2 is stopped by a stopper, etc., and the engaged state between the protruding part 9 for engagement and the part 13 to be engaged is released, and the lock pin 4 is pulled out from the die 2, and the dies 2, 3 are separated as well. Thus, the adjustment work for the tightening strength of a bolt can be eliminated.

IPC: H03M1/08
Filed: 1988-07-11
Abstract: PURPOSE:To suppress distortion or a noise due to the overload on the gradient of an analog waveform at minimum by varying step size i.e., sampling size. CONSTITUTION:A count-up clock or a count-down clock is selected by a signal selector 5 by sending signals in the case of attaching steep inclination and moderate inclination on an input analog signal, and it is sent to an up/down counter 6, and the parallel output of the up/down counter 6 is sent to a waveform converter 7. And the waveform converted output of the step size is converted from the waveform converter 7 by a sign from a sign comparator 3, then, it is sent as digital modulated output.
